The apparatus consists of [1]A ⅛ inch thick by one inch wide by ten inch length steel plate bent and twisted in a manner to hold both bolt and rebars. [2] A square steel tube one inch by one inch by one inch with ⅛ inch wide by ½ inch deep notch to be used in conjunction with above mentioned strong arm. [3] A ⅛ inch thick by one inch wide by seven inch length steel plate with the top portion bent over one inch with a ⅝ inch hole to accommodate a foundation bolt and two ⅝ inch notches to hold top and bottom rebar. [4] A ⅛ inch by 20 inch steel rod bent in a described manner to hang the top and bottom rebars from above described strong arm and independent of claim  2.  [5] A ⅛ inch by 6 inch steel rod bent in a described manner as to hold 2 foundation rebars independent of components 1 through 4.

FIELD OF THE INVENTION

The present invention relates to the construction of buildings with atypical exterior foundation known as footings. The invention creates asystem for securing the foundation bolts and hangs the foundation steelbars known as rebars.

BACKGROUND OF THE INVENTION

For many years buildings used for homes or commercial use have beenbuilt in a manner that lacks structural integrity. In areas that aresubject to earthquakes, tornadoes, and hurricanes, it is of utmostimportance that the foundations are constructed with great strength.

In previous years foundation bolts were made of smaller diameter andshorter lengths and merely pressed down into wet concrete after it waspoured. This resulted in small voids around the bolt which resulted inweaker structural strength.

It is of utmost importance that foundation bolts when placed in theirrequired position stay without movement while the concrete is pouredaround them. New building codes require these bolts be placed inposition prior to concrete being poured.

Building codes require that the foundation rebars be positioned in amanner that prevents them from coming in contact with earth. The currentmethod for achieving this is to place the bottom rebar on cement blocksand hang the top rebars by tie wires to the forms or stakes above.

SUMMARY OF THE INVENTION

The object of the invention is to secure the foundation bolts in amanner to stay at an exact height and held in an exact distance from theedge of the slab. This invention system also hangs and secures as manyas four foundation rebars in the required location in the footings byhanging from the metal strong arm.

DETAILED DESCRIPTION

The following detailed description represents the best currentlycontemplated modes for carrying out the invention. The description isnot to be taken in a limiting sense, but is made merely for the purposeof illustrating the general principles of the invention, a fivecomponent bolt and reinforcing bar system.

Referring to FIG. 1, a component hereafter known as component A thatworks in conjunction with component B [FIG. 2]. The square metal tube 11is a one inch by one inch by one inch long tube with a ⅛ inch wallthickness. This tube has a one inch wide by ½ inch deep notch. 12 onboth sides by the side wall, this leaves a ⅝ inch clearance to allow a ⅝inch bolt to pass through. On the opposite side walls it has two ⅛ inchholes 13 at the top and bottom to receive two keeper pins 14. The ⅛ inchnotches 12 of the metal tube 11 slips over the horizontal bar of themetal strong arm 18. The bottom pin hole 13 is aligned with the pin hole13 in the metal strong arm 18 to lock it in place with the keeper pin14. The foundation bolt 25 is then placed up through the tube 11 [seeFIG. 9].

Referring to FIG. 2, known as component B. This is a ⅛ inch thick by oneinch wide by 11 inch long flat metal plate with a 4 inch verticalportion 17 then bent at 90 degree 15 with a full twist 16 to create thehorizontal portion of the strong arm This seven inch long arm has four ⅛inch pin holes 13. The vertical portion 17 is designed to nail to theside of a wooden form board [see FIG. 10]. This component is designed towork independently of the metal tube 11 to support the third componentknown as component C, a ⅛ inch steel rod shaped to support tworeinforcing bars 32 [see FIGS. 3 & 10].

Referring to FIG. 3, component C, a ⅛ inch by 21 inch steel rod shapedas follows, a ½ inch long horizontal portion 21 then bent 95 degreesdownward 20 to create a vertical member 19 eleven inches long, bentagain at 90 degrees 22 to create a ⅝ inch wide horizontal portion, thenbent upwards 90 degrees 22 for one inch vertical, then bent downward 180degrees 23 to a vertical portion six inches long 19 then again bent 90degrees 22 for a ⅝ inch horizontal portion then 90 degrees upward 22 fora one inch vertical arm 24. This component is designed to accommodateholding a top and bottom reinforcing bar 32 [see FIG. 10], and to hangfrom strong arm 18 by slipping horizontal portion 21 through pin holes13 [FIG. 2].

Referring to FIGS. 4 & 5, describes a side elevation and a frontelevation of the fourth component of the strong arm bolt and rebarsystem, Component D. This component is a ⅛ inch thick by one inch wideby seven inch long flat metal plate. Looking at the side elevation,[FIG. 4] a horizontal length one inch 36 with a ⅝ inch hole 40 bent at90 degrees downward 35 to create a six inch vertical member 34. Thisvertical member 34 has a ⅝ inch wide elongated downward notch 37 at thetop and bottom portion to hold a top and bottom reinforcing bars 32 [seeFIGS. 6 & 10].

Referring to FIG. 6, this describes a full dimensional view of FIGS. 4 &5 and how this component is designed to be used. The horizontal member36 with it's ⅝ inch hole 40 is placed on a ⅝ inch by 12 inch foundationbolt 25 which is supported by the strong arm components of FIGS. 1 & 2[see FIG. 9]. The two downward ⅝ inch elongated notches support the topand bottom reinforcing bars 32 see FIG. 6. This bolt and rebar system isaccomplished by the three components of FIGS. 1, 2, & 4 [see FIG. 10].

Referring to FIG. 7, this is a fifth component of the rebar systemdesigned to be used in footings where no wooden forms can be used tohang the reinforcement bars with the use of the strong arm 18 of FIGS. 2& 3. It is a 3/16 by 10 inch steel rod bent as described. A ¾ inchvertical arm 26 then bent 90 degrees 27 with a ¾ inch long horizontalarm, then bent 90 degrees upward 27 for a ¾ inch vertical arm, then bent120 degrees downward 28 for a one and ½ inch arm 29, then again bentdownward at 45 degrees 30 for one inch, then 180 degree bend upward 31for one inch vertically, then again bent upward 45 degrees 30 for oneand ½/inches 29 to a 120 degree downward bend 28 for a ¾ inch verticalarm, again bent 90 degrees 27 for ¾ inch horizontal, then bent againupward 90 degrees 27 to a ¾ vertical arm 26.

Referring to FIG. 8, this is a full dimensional view describing the useof a fifth component [FIG. 7]. This describes the devise in usesupporting two foundation reinforcing bars 32 with the use of a hollowpipe 33 driven down in the center of a footing. The portion of thedevise 31 is placed down into the pipe to support both side arms 29 bentoutward from the bends 30 and 30.

Referring to FIG. 9, this is a full dimensional view of the first twocomponents A & B used over a typical exterior footing where they can beattached to a wooden form 38 [see FIG. 10].

Referring to FIG. 10, this is a full dimensional view of an exteriorfooting and all of the components used in conjunction with a wooden formboard 38.
